Features
■ Ready-to-use printed circuit board (PCB) with: – 20 mm x 40 mm 13.56 MHz inductive antenna etched on the PCB – STM8L101K3 8-bit microcontroller – STTS75 temperature sensor – CR2330 battery – ON/OFF switch – SWIM connector for microcontroller firmware upgrade
Description
The DATALOG-M24LR-A is a ready-to-use PCB that features an M24LR64-R Dual Interface EEPROM IC connected to an STM8L101K3 8-bit microcontroller through an I 2C bus on one side, and to a 20 mm x 40 mm 13.56 MHz etched RF antenna on the other one side. The STM8L101K3 is also interfaced with an STTS75 temperature sensor and a CR2330 coin cell battery. The DATALOG-M24LR-A allows system designers to start developing a standalone or an embedded datalogger. The DATALOG-M24LR-A reference board is supported by ST DEVKIT -M24LR-A, STARTKIT - M24LR-A and DEMOKIT -M24LR-A evaluation kits, for which a demonstration software is available. The reference board Gerber files can be downloaded from http://www.st.com. Figure 1. DATALOG-M24LR-A block diagram
Associated firmware and PC software DATALOG-M24LR-A 2/4 Doc ID 17870 Rev 2 Associated firmware and PC software The DATALOG-M24LR-A is delivered with:
- An on-board demonstration firmware, the M24LR64- R_Datalogger_application_firmware, that selects and controls the temperature acquisition through a RFID reader connected by a USB cable to a PC
- A PC software, the M24LR64-R_Datalogger_application_software, to configure and control the datalogger, as well as download and display the temperature values. The firmware source files, the PC software are available from http://www.st.com.
